O que é e para que serve o centro de saúde? - The BME sensor module reads barometric pressure, temperature, and humidity. Because pressure changes with altitude, you can also estimate altitude.

Breakout boards, sensors, Drawdio, Game of Life, other Adafruit kits, etc.

I'm using code from BoschSensortec's github. I am getting reasonable values for pressure and humidity. But since the comp data is zero, it just zeros out the temp when compensated. So if it's a code error then it's in the github code. The lack of others having this problem can't find anyone complaining in a search makes me wonder if I just have a chip not calibrated. Any advice? The SparkFun BME Atmospheric Sensor Breakout is the easy way to measure barometric pressure, humidity, and temperature readings all without taking up too much space.

Basically, anything you need to know about atmospheric conditions you can find out from this tiny breakout. The on-board BME sensor measures atmospheric pressure from 30kPa to kPa as well as relative humidity and temperature. The breakout provides a 3. The BME Breakout board has 10 pins, but no more than six are used at a single time. The left side of the board provide power, ground, and I 2 C pins. The remaining pins which provide SPI functionality and have another power and ground, are broken out on the other side. Note: The breakout does NOT have headers installed and will need to purchased and soldered on yourself.

Check the Recommended Products section below for the type of headers we use in the Hookup Guide! This module is not suitable for high-altitude balloons, despite its perfect size. Only goes to 30, ft, while high-altitude balloons go to at least 60, ft generally. This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools. Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple if any polarized components. A basic soldering iron is all you should need.

See all skill levels. If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code. Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code.

You may need to modify existing libraries or code to work with your specific hardware. If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics. Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

We welcome your comments and suggestions below. However, if you are looking for solutions to technical questions please see our Technical Assistance page. Hey everyone. There's a few comments here that have to do with the sensor being a few degrees high and I wanted to discuss it. Specified Accuracy I looked up datasheets on the various sensors this is being compared to.

Here's the take-away:. Some of the discussion says that maybe the location in the circuit effects the temperature. Noting that self-heating could possibly effect the temperature, I devised a quick experiment to test this. I can confirm, that readings seems to be high compared to other I2C sensors. Since all available BME libraries give similar results i assume, there could be a misinterpretation of calibration values or a not yet discovered problem with the datasheet. I set up a small test on 3. The documentation is lacking dimensions for the board.

Makes it difficult to design a case which uses this board without first purchasing all the bits and then measuring by hand. That, or install Eagle and read the board files : Can Sparkfun please include a simple dimensions drawing in their documentation as a matter of routine? These boards aren't compatible with 5 volts. See the BME absolute ratings in the datasheet Hi there, Would the BME sensor be suitable for use outdoors during the winter? I'm looking for a good sensor to deploy in the Canadian Arctic, which would remain outdoors for an entire year. I'm just wondering if condensation might be an issue over time. If you look at page 31 of the BME datasheet, it says:.

The last bit is changeable by SDO value and can be changed during operation. It specifically says that it should not be left floating, but either connected to GND 0x76 or Vddio 0x It's not floating. If you check the schematic you will see that it's pulled high by default through a 4. There's also a jumper on the board that allows you to set it high or low manually, or if you leave it high you can externally pull it low through the SDO pin on the edge of the board. CF - you are entirely correct! I don't know which Eagles I looked at, when I posted this! But if you leave it floating, the datasheet says it is "undefined", what does this mean? That you can't be certain which I2C address it has?

Or it simply does not have one at all? Just a quick note on the library. The hookup guide says that pressure is returned in kilopascals, but unless I'm deep under the ocean and nobody told me, it's just returning pascals. The temps all rise and fall together, but the BME is between 5 and 9 degrees F high. The thing should be delivering 3. This is so far off I'm tempted just to call it defective or miscalibrated and order a replacement. It's a shame we can't somehow fix the calibration by taking known temps. Could be a very simple question. Is this water resistant? I have a PVC rain tower. I want to know what the RH is inside. Obviously the board will get wet. I will use heat shrink on the wiring.

The datasheet says condensation is allowed, but I don't know if immersion will damage the sensor or the breakout board. Is there a Frizting file available for this? I can't find one, but it looks like the Hook-Up guide is using one. There is! We're working to get our Fritzing parts included with the program but we're not there yet. I got this breakout board from a reseller in Germany but all values are way off. Even the temperature shown by the BME is about 3 degrees Celsius higher than the real temperature and altitude is about metres to low.

Is there any calibration necessary before first use?
